What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Controlled WPEngine Cache Busting

This technique was used to control WPEngine's caching by making WPE think there was a WordPress CMS user logged in by setting a fake cookie.

This code was developed to display site-wide dynamic content when a user authenticated against an external (non-WordPress) service.

N.B.: this worked as of 10/2015, but WPE may make infratructure changes which break the technique.

Usage

<?php

/**

 * @param $request_or_method WP_REST_Request|string A WP_REST_Request object or a request method
 * @param $path (optional) if the path is not specific in the rest request, specify it here
 * @param $data (optional) option data for the request.
 * @return WP_Error|mixed

# What if you are trying to migrate a bunch of posts from one site into
# another site that already has content? We'll assume you already  have
# a database export of the posts and postmeta you want to migrate. You
# will want to create a database locally to alter the tables to get them
# ready to merge into the production database that already has content.
# You will also need to know the highest `meta_id` and `ID` values from
# the `wp_postmeta` and `wp_posts` tables, respectively.

# First, we need to create new columns in the tables we have locally. To
# do this the right way, we are going to figure out what type of data
